This is good advice--and Hika is almost definitely correct in his 
suggestion that the problem is misconfigured input sources (capture 
cards, video sources, channels, and/or their linkage).  However, the 
"solution" ("Delete All Video Sources") will only be a solution if it's 
followed by properly configuring them the next time (versus repeating 
the same mistake you made the first time--likely why it's not working 
for you).  Note that starting over with a new install of MythTV--which 
does absolutely nothing--won't help.  Starting over with a new database 
(i.e. after "DROP DATABASE mythconverg;") would do nothing more useful 
than the "Delete All Video Sources" approach--and would actually remove 
any configuration you've actually got correct, too.  So to make things 
work, you're going to have to redo the process (after a "Delete All 
Video Sources") and not make the mistake you've been making.

Usually, the mistake that results in the symptom you're experiencing is 
a failure to associate the MythTV Video Source's channels with the 
Schedules Direct lineup's channels--meaning the XMLTV IDs aren't 
properly set.  See 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 . I'm 
guessing that you're probably using a digital source (meaning you need 
to scan for channels), and the broadcast channels themselves don't 
provide sufficient information to match up with the information 
Schedules Direct has--so you'll probably need to manually configure the 
XMLTV IDs, as described on the linked wiki page.  Most likely, you're 
currently relying on mythfilldatabase to figure out which of your 
scanned channels matches with which of Schedules Direct's listed 
channels, and it's failing to do so (it's never guaranteed--it's only if 
you're lucky enough to have channels with sufficient identification 
information broadcasted /and/ if that information happens to be the same 
as the information that Schedules Direct has).
